摘　　要：基于因子分析法测算了城市经济实力,运用可达性系数模型分析高速铁路和高速公路对城市可达性的影响,运用引力模型测算出快速交通对城市经济联系的影响,并利用ESDA法测度了城市经济联系的空间分异特征。结果表明:快速交通使得湖南城市整体可达性大幅提高,产生了明显的"时空压缩"效应。快速交通使边缘城市与中心地区城市可达性的差异缩小,高铁沿线城市的可达性明显优于非高铁沿线城市,高速公路扩大了高铁可达性的影响范围。快速交通使湖南省内城市间经济联系增强,强化了长沙的经济中心地位,扩大了东西部城市的经济差异,省际经济联系强度受出省通道便捷性的影响。此外,各市经济联系总量总体上具有层次性,演化上存在非均衡性。The economic strength of the city is calculated based on factor analysis.Using accessibility coefficient models to analyze the impact of high-speed railways and expressways on urban accessibility.Using gravity models to measure the impact of high-speed railways and highways on urban economic connections.And use ESDA to measure the impact of accessibility on economic space.The results show that the rapid traffic has greatly improved the overall accessibility of Hunan cities,and produced a significant“space-time compression”effect.Rapid transportation reduces the difference in accessibility between peripheral cities and central cities.The accessibility of cities along the high-speed rail is significantly better than that of non-high-speed rail cities.Highway expand the accessibility of high-speed railways.Rapid transportation has strengthened the economic ties between cities in Hunan Province,strengthened Changsha’s position as an economic center,and weakened the economic gap between the east and the west.The intensity of inter-provincial economic ties is affected by the convenience of access to the province.The total economic linkages of each city are generally hierarchical and uneven in evolution.
